Modernisation work on the first batch of helicopters will be carried out for the Russian Navy and is due to be completed by the end of 2015.

Ka-27PS helicopters are used in search and rescue operations, and the Ka-27PL is designed to identify and destroy enemy submarines.

The export variant is the Ka-28, that has been supplied to countries including ‎India‬, ‪‎Vietnam‬, and ‪‎China‬.

The Ka-27 modernisation programme will make it possible to offer foreign states the opportunity to modernise those Ka-28 antisubmarine helicopters that are in operation or to purchase new Ka-28s boasting enhanced capabilities.
